Week 2 Challenge
Ans 1.1.
for assigning the circular section in the column just go to the property and select the define then you have a window then select the circule and specify the readious of the column then select the define material and assign to view
Ans1.2.
To Assignt unit system in the staad pro
Go to file menu and then settings
open the structural option and select the structure units
Change the dimesions as the required units
Ans 1.3.
To create the parameter of the design by Bay frame
By clicking on the Structural wizard option
Click on the frame model option
click on the Bay frmae option
Enter the parameters like the lenght , breadth , height and the bay frame along the length , breadth and height
Ans 1.4.
In Staad pro the Codal standard are incorported for the Steel , Concrerte , Aluminium.
For the Steel the codal provision are IS 800 , IS 800 : 2007 , IS 800:2007 WSD , IS 801
For the concrete the Codal provision are the IS 456 and IS 13920 for the Sismic Design
Ans 1.5.
Go to the Design option
Click on the define parameter
In the design Parameter the FYLD Compressive strength of RCC section is Given as 25000 KNm
Ans 2.1.
Steps Involved in RCC design are
1. Geometry : The Node loaction and the node spacing are given
2. Properties : Specify the Sectional properties of the section
3. materials : Specify the properties of the material
4. Specifications : The pecifictions are given
5. Support : The end support are to be given
6. Loading : Need to provide the loading pattern and the loading combination
7. Analysis : Need to Analysis the modal and all the Input Specification are Given
8. Design : Finally the Design are to be done
Ans 2.2.
In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.
For the ENFORCED BUT type, there is no provision to specify a spring constant.
The only choices, which are built into the program, are - zero stiffness
Ans 3.1.
The steps involved in analysis of a model are
Before Analysis the model the load pattern and the load combination are to be provided to the model
Then go to Analysis option
Define Command
Select the data for the analysis of the model by perform analysis , P delta analyis ,Nonlinear analysis
It deponds upon the support conditions
Ans 3.2.
The two ways to model the a structural framework is
1. Creating model by Node by Node
2. Creating model by Bay frame by
Ans 3.3.
Ans 3.4.
The Design of Staircase slab is done by Node placement
The creation of plate is used in stair case
BY using Generate mesh
The stress distribution for the staircase slab is done by viewing colour in the slab of the design
Ans 3.5.
After complation of the Design the staad pro will automatically provide the BMD & SFD
By Entering to the Post procesing process click on ok
By clickin the beam results Deflection command
Reaction click the beam deflection
PRACTICAL:
AIM:
- To draw a 20m length of simply supported beam with two pint loads symmetrically placed and load p = 50 kN each,both P placed at 5m from each support.
- And a 16m lenght of fixed beam with uniformly distributed load w = 9 kN/m
Prcedure:
A. Simply Supported Beam.
- Open the staddpro software
- Define the units as per below image
Add beams as per below image
Then draw 20m length line with node
And the concrete material with 0.23 x 0.23 thickness as per below image
Then add the supports :- simply support to each node
then add Load P = 50kN each
Both P located at 5m from each support
Then select the loads & defination
Add load case details 
Then run analysis.
There is no error in file see attached the below image.
See the load case displacement 
B. Fixed Beam.
Draw the 16m length beam
Define the the support as fixed 
Then add the concrete material with 0.23 x 0.23 thickness as per below image
Then assign the loads 
Then run analysis.
There is no error in file see attached the below image.
See the load case displacement
See the load case 2 
See the Reactions 
RESULTS:
Simply Supported Beam and Fixed Beam are drawn successfully
